Radicals

Radicals

1. Simplifying Radicals

   • When it's not a fraction, and when it has no more square factors.

2. Adding and Subtracting Radicals

   • To add radicals you have to have the same number in both of the radicals. You have to add and subtract "like" variables.
   • Radicals must be the same before you add or subtract them. Not the outside number, the number in the radical sign.
   • You add and subtract the diff. numbers in front of the radical sign. The numbers under the sign are alike.

3. Multiplying Radicals

   • Multiply the numbers outside the radical sign, and then multiply the numbers inside the radical sign.

4. Radical

   • Looks like a square root sign. But it can also be used to describe the cube root, fifth root, and much higher.
